PURPOSE: This study aimed to describe the pattern of injuries and illnesses among Korean athletes during the Almaty Winter Universiade 2017. METHODS: All medical staffs of Korean team recorded the daily occurrence of injuries and illnesses sustained during the Almaty Winter Universiade Games by using a standardized online form via kociss.com. The design of this study was a prospective study. RESULTS: In total, 98 athletes (68 men and 30 women) in 11 sports events from Korean Sport Olympic Committee participated in this study. Korean medical staffs reported 40 injuries (40.8%) and 26 illnesses (26.5%), equaling incidences of 6.3 injuries and 4.1 illnesses per 100 athletes. Men suffered more injury and illness than women (44.1% vs. 33.3%). The rate of Injury and illness in training was higher than the competition (13.3 vs. 2.0 athlete exposures). The risk of an athlete being injured was the highest in freestyle skiing, followed by snowboard and speed skating. Overall, the main common type and location of injury was the joint or ligaments sprain (13.3%) and knee (7.1%). The rate of main illness was 17.3% of the respiratory system with the main symptom of pain and the main cause of environment (22.4%). CONCLUSION: Injuries and illnesses occurred 40.8% and 26.5% during this winter game, and were higher during training than a competition. Based on the epidemiologic data of this study, it could provide the source for the injury prevention and improving the performance of the athlete and further develop scientific injury and illness surveillance systems.

Pentastomiasis, a zoonotic parasite infection, is typically found in the respiratory tract and viscera of the host, including humans. Here, we report for the first time an extremely rare case of intraosseous pentastomiasis in the human maxilla suffering from medication related osteonecrosis of the jaw (MRONJ). A 55-year-old male had continuously visited the hospital for MRONJ which had primarily developed after bisphosphonate and anti-neoplastic administration for previous bone metastasis of medullary thyroid cancer. Pain, bone exposure, and pus discharge in the right mandible and left maxilla were seen. Osteolysis with maxillary cortical bone perforation at the left buccal vestibule, palate, nasal cavity, and maxillary sinus was observed by radiologic images. A biopsy was done at the left maxilla and through pathological evaluation, a parasite with features of pentastome was revealed within the necrotic bone tissue. Further history taking and laboratory evaluation was done. The parasite was suspected to be infected through maxillary open wounds caused by MRONJ. Awareness of intraosseous pentastomiasis should be emphasized not to be missed behind the MRONJ. Proper evaluation and interpretation for past medical history may lead to correct differential diagnosis and therapeutic intervention for parasite infections.

PURPOSE: The purpose of this study was to identify international students' use of university health centers by individual characteristics and seasons. METHODS: This was a retrospective descriptive study using data obtained from the electronic record system of one university health center. The study participants were international undergraduate students who registered for any of two semesters between March 1, 2014 and February 28, 2015 and visited the university health center during their registration period. RESULTS: The most common reasons for visits were problems of head, eye, nose and throat systems, followed by respiratory system. Their visits mostly occurred in the fall and spring. The most frequently used services were distribution of oral medication followed by wound treatment. The number of visits per individual was statistically different by gender (u=-3.307, p=.001), but not by their major (chi2=.543, p=0.762) or nationality (chi2=5.518, p=.271). CONCLUSION: Further study is necessary to better define health needs and related factors for this unique population. The electronic record system provides great opportunities in development and application of need based health services for international students and for research in this area.

PURPOSE: The purpose of this study is to understand what kinds of chemical substances have been used annually and to investigate incidents that occurred due to chemical hazard release and to analyze statistically clinically chemical injury patients who visited one regional emergency medical center in Gumi city with documented references review. METHODS: Annual chemical waste emission quantity (Kg/Year) (Cwep) was reproduced using national web site data governed by the Ministry of Environment and 5 years (from 1 .Jan. 2010 to 31. Dec. 2014) of medical records of chemical injury patients who visited our emergency department were reviewed retrospectively. By applying exclusion criteria, 446 patients of 460 patients were selected. RESULTS: Dichloromethane, Toluene, Trichloroethylene, and Xylene were always included within Top 5 of Cweq. Six cases of chemical incidents were reported and in 3 of 6 cases involving Hydrogen fluoride were included during the study period. Male gender and twenties were the most prevalent group. Injury evoking chemicals were Hydrogen fluoride, unknown, complex chemicals (over 2 substances) in sequence. The most frequent site of wounds and injuries was the respiratory tract. Gas among status, intoxication among diagnosis, and discharge among disposition was most numerous in each group. CONCLUSION: There have been no uniform clinical protocols for chemical wounds and injuries due to various kinds of chemicophysical properties and ignorance of antidotes. Therefore conduct of a multicenter cohort study and experiments for ruling out chemicals according to chemicophysical priority as well as development of antidotes and clinical protocols for chemical injury patients is needed.

BACKGROUND: Preemptive analgesia is known to decrease the sensitization of the central nervous system and reduce subsequent amplification of nociceptive stimuli. We investigated whether preemptive thoracic epidural analgesia (TEA) demonstrated intraoperative and postoperative short and long term clinical advantages. METHODS: Thirty patients scheduled for open thoracotomy were randomly allocated to one of two groups to receive continuous TEA (0.15% bupivacaine and 8 microg/ml hydromorphone) either before surgical incision (preemptive group) or at the end of the operation (nonpreemptive group). Incidence of hypotension during surgery was recorded. Numerical rating scales (NRS) and the incidence of side effects such as nausea, pruritus, sedation, hypotension, and respiratory depression were recorded at 2, 6, 24, and 48 hours postoperatively. Pulmonary function test (PFT) was performed before, 24 and 48 hours after the operation. Persistence of pain control was investigated at 6 months postoperatively. RESULTS: The NRS score, side effects, and PFT changes were comparable between the two groups. TEA and intravenous rescue morphine consumed at 2, 6, 24, and 48 hours postoperatively were not different between the two groups. During surgery, the incidence of hypotension was significantly higher in the preemptive group (P = 0.027). At 6-month follow up, two patients in the nonpreemptive group complained of persistent pain at wound and none in the preemptive group. CONCLUSIONS: Preemptive TEA with hydromorphone and bupivacaine during surgery may cause unnecessary intraoperative hypotension without a prominent advantage in reducing acute or chronic pain or enhancing pulmonary function after thoracotomy. The advantageous concept of preemptive TEA may be dubious and may not provide perioperative clinical benefits.

OBJECTIVE: To assess cough reflex sensitivity using the simplified cough test (SCT) and to evaluate the usefulness of SCT to screen for silent aspiration. METHODS: The healthy control group was divided into two subgroups: the young (n=29, 33.44+/-9.99 years) and the elderly (n=30, 63.66+/-4.37 years). The dysphagic elderly group (n=101, 72.95+/-9.19 years) consisted of patients with dysphagia, who suffered from a disease involving central nervous system (ischemic stroke 47, intracerebral hemorrhage 27, traumatic brain injury 11, encephalitis 5, hypoxic brain damage 3, and Parkinson disease 8). The SCT was performed using the mist of a 1% citric acid from a portable nebulizer. The time from the start of the inhalation to the first cough was measured as the cough latency. All the dysphagic patients underwent the videofluoroscopic swallowing study. RESULTS: The cough latency was more significantly prolonged in the healthy elderly group than in the healthy young group (p<0.001), and in the dysphagic elderly group than in the healthy elderly group (p<0.001). The sensitivity and specificity of SCT were 73.8% and 72.5% for detecting aspiration in the dysphagic patients, and 87.1% and 66.7% for detecting silent aspiration in the aspirated patients. CONCLUSION: Cough latency measured with the SCT reflects the impairment of cough reflex in healthy elderly and dysphasic subjects. The results of this study show that the SCT test can be a valuable method of screening aspiration with or without cough in dysphasic patients.

Acute organophosphate intoxication is important because of its high morbidity and mortality. The mortality is still high despite the use of atropine as specific antidotal therapy and oximes for reactivation of acetylcholinesterase. Inhibition of acetylcholinesterase by organophosphate can cause acute parasympathetic system dysfunction, muscle weakness, seizure, coma, and respiratory failure. Acute alteration in conscious state or a coma, which may occur following organophosphate intoxication, is an indication of severe intoxication and poorer prognosis. This acute decline in conscious state often reverses when the cholinergic crisis settles; however, it may be prolonged in some patients. We report on a case of a 60-year-old male who showed prolonged decline in conscious state due to of Central Nervous System (CNS) toxicity after a suicide attempt with organophosphate.

OBJECTIVE: To develop criteria to assess injuries due to diethyl sulfate poisoning. METHODS: Patients were evaluated with respect to their toxic status and outcomes, in comparison to typical cases. RESULTS: Among 44 poisoned patients, 4 patients were classified as major injuries, 4 person as minor injuries, and the rest of 36 patients were classified as not poisoned according to poisoning diagnostic criteria by No.GBZ40-2002 "Diagnostic Criteria of Occupational Acute Diethyl Sulfate Poisoning". CONCLUSION In assessment of the injuries caused by diethyl sulfate poisoning, one should follow diagnostic criteria set by National Occupational Acute Poisoning due to Chemicals and Drugs and "Criteria for Assessment of Human Body Injury."

Enterobacter cloacae, a gram negative bacillus is an increasingly frequent cause of nosocomial pediatric infection. It can cause infection of postsurgical wounds, meningitis, and infection of the gastrointestinal, urinary, and respiratory tracts. Newborn infants often are colonized by Enterobacter species in the gastrointestina tract or respiratory tract soon after birth, and a acquisition of hospital strains in immunocompromised newborn infants is common. Neonatal pneumonia has been associated with many infectious agents. Pneumatocele, a cyst-like lesion that develops within the lung parenchyma, is an unusual complication of pneumonia in the neonate, especially in the preterm neonate. Pneumatocele has been reported to occur with Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Streptococcus pneumoniae, and Pseudomonas aeruginosa infections. We describe 2 cases of premature neonates with pneumonia and subsequent pneumatocele formation caused by Enterobacter cloacae.

BACKGROUND: Prevotella species is one of the major microoranism responsible for invasive anaerobic bacterial infection. This study was performed to investigate the clinical characteristics and outcome of invasive Prevotella infection in a University affiliated, tertiary care Hospital. METHODS: We obtained the information from the computerized data base of the clinical microbiology laboratory from January 1997 to December 2000, and identified patients whose sterile clinical specimen culture had yielded Prevotella species. We then reviewed the patients' medical records, and studied demographic, clinical, and microbiologic data. RESULTS: The total of 34 patients with invasive Prevotella infection were enrolled for the analysis. Seventeen strains were isolated from blood, 13 from the pleural fluid, 5 from the ascites, and 1 from both the ascites and blood. Half of the cases of Prevotella infection were mixed-infection and 22 cases (64.7%) were of community origin. Twenty-six patients (76%) were men and the mean age was 59 years. Most common underlying disease was malignant neoplasms (19/34, 55.9%). A portal of entry could be determined in 29 patients (85.3%) with the most common being the respiratory tract (12/34, 35.3%), followed by the gastrointestinal tract (6/34, 14.4%), and the wound site (6/34, 14.4%). Surgical procedure was necessary for 21 cases (63.5%). One-month mortality was 32.3%. The mortality was significantly associated with the underlying chronic renal failure (p=0.028) and ICU care (p=0.002). Surgical therapy had a protective effect (54% vs 14%, p=0.022) CONCLUSION: Invasive Prevotella Infections were more prevalent among old age patients with underlying malignancy than younger people and frequently necessitated surgical procedure. Early surgical treatment would decrease mortality.
